How many types of dialysis are there?

There are two main types of dialysis: hemodialysis and peritoneal dialysis. Hemodialysis involves the use of an artificial kidney machine (dialyzer) to filter wastes and excess fluids from the blood, typically performed at a dialysis center or at home with specialized equipment. On the other hand, peritoneal dialysis uses the lining of the abdominal cavity (the peritoneum) to filter blood, where a special solution is infused into the abdominal cavity to draw out waste products.

This distinction between the two methods highlights the primary approach used to manage patients with renal failure, focusing on how the dialysis process influences the treatment of kidney function. Understanding these two types is crucial for medical coding, as they relate to different CPT codes and billing practices associated with renal therapies.

Other options suggesting a higher number of dialysis types may refer to variations or specific techniques within these two main categories but do not represent distinct forms of dialysis recognized in clinical practice. Therefore, identifying two key types accurately reflects the established medical terminology and coding practices.
